You lost 200k? Really? I find that hard to believe. What exactly happened? A client crash (or server crash) can't make money disappear if it is in your inventory, really.
I've been collecting some money for my guild, and had 800k in my inventory that morning. I counted it besides Harnquist last where I used the furnaces to smelt the platinum. After smelting, I turned around, and there was a huge lag. Not something new, it happens like that each time for me at least. But this time it was much longer... no other window was responding either. I went out to check my mailbox, met a friend on the way, had a little chat with her, came back after 30 mins and the client was still unresponsive, though hard disk LED was blinking. Finally I saw the infamous BSOD and my macbook running windows xp via bootcamp decided to restart itself. After the restart, I logged in again, and found only 600k in my inventory.
I asked around if pickpocketing has been implemented, and the answer was no.
I quit playing from 1st June because of study pressure, so that lost money means nothing to me now. Maybe something for the developers to work on!
